vTo 7l whom #may concern:

Be it known that 1, HAaoLo D. Grinsen," a citizen oi the United States, and resident Detroit, l'v'flayne County, State of Mich- ,he E have invented certain new and usciul improvements in Hydrocarbon Motors, ot `which the Afollowing is a specification.

rlhis invention relates to hydrocarbon rnotois and particularly' to the cooling ot the cylinder biocirs.

Une oi' the niost diliicult parts of a hydrocarhon motor to cool is the valve seats, particularly the exhaust valve seats. 1t is desirable that the remainder of the motor shall be operated as hot as it can he run Withoutpreigniting the'charge. `With all of the hot gases passing over the exhaust valve seat, the seau'and consequently theI valve, if run constantly under heavy load, will sometimes get too hot and cause burning. Because the exhaust valve seat is frequently located very close to the cylinder Wali it is diiiicuit to get ail of the core sand out and maire a, clean and uniform Water jacket aro-und the sea-t.

@ne of the objects or the present invention is to more efectiveiy cool the exhaust valve of a hydrocarbon. motor, and this and the other objects and advantages of the invention will appear from the following descrip'tion taken in connection with the drawings which forni part o' this specification.,` and in Whici t Fig. 1 is a side elevation of hydrocarbon motor embodying this invention;

2 is a` transverse section of the motor in Fig. 1, on the line 2-2 ot Fig. 1;

Fig. 3 is a horizontal section ot a hydrocarbon motor illustrating another form ot' the invention, the right hait being in a pl ne somewhat above 'that ot the lett halt;

's a detaii view ot one of the water Fifi e Paeieiring to the form of the invention` shown in iFigs. 1 and 2, 1() represents thev crank case oi a hydrocarbon motor upon `which is mounted the motor cylinder block 11. 1Water circulation through the cylinder hloclr is caused by a pump 12 which conveys Water to the bioclr through a `pipe 13, and a pipe iet carries the Water from lthe block to radiator 15, the system of circulation specification @framers Patent.

being completed by a pipe 16 from the bottom of the radiator to the pump 12. .fr

inlet and an exhaust valve for each cylinder..

1n Fig. 1 two inlet. ports 19 are shown and it Will-be understood that, these ports branch Wit-hin the casting and each of them leads to two of the cylinders of the block, There 1s, however, an exhaust port 20 for each of the four cylinders-and the section shown in Fig. 2 is taken through one of these exhaust ports. Fie. 2 also shows. the valve seat 21 which is Iormed as a part of the cylinder block.

The block 11 is formed 'with a jacket 22 which may, as shown, be in part an integral portion of the block and in part formedr by pla-tes such as 23 and 24 to permit of good core work. At all events, the jacket extends around the upper part of the cylinder and around the valve seats and in this form ot' the invention the Water is taken from the top of the cylinder jackets through the pipe 1-1 which leads to the radiator.

Instead of teedinr the WaterA 'from the ja'clreted block, the present invention conl templates carrying the Water into the block by means of a conduit which has several openings dircctingthe Water' from the conn duit towards the seat-s ot' the exhaust valves. As shown in said Fi4 1 and 2, the, pipe 13 connects with a con uit 25 which is preterably cast into the block Whenjshe latter is made and is arranged longitudinally of the block and beneath the valve seats. The position of this pipe isparticularly Well shown in the figures, the plate 24 being partly cut away in Fig. 1 so that the pipe may be better seen. The pipe 25 has a series of openings 26 'which are arranged adjacent the exhaust valve seats so that the Water issuing :from these openings Will be directed toward said seats Within the jacket or the bioclr. @t course this Water that comes directly from the pump 12 is the coolest Water in the system, having just passed through the radiator 15, and the exhaust valve seats is consequently reduced in spite of the reim tively i-oat amount ci heat to which theyare subjected. Opening 25 lforms a drain for the pipe 25.

In the forni of the invention shown 1n r`l5`i,fs. 3 to 6 inclusive the ,parte of the cylthepump has two branches 27 and 28 which y lead respectively to the front and rear parts of the cylinder block, and each of these branches connects with a conduit orpipe those valve seats.

a which, like the pipe 25 of' the other form of the invention, is preferably cast in the cylinder block. Each of the pipes 25a is formed with two branches or outlets 29 aI1 d v 30 which lead to points directly beneath the exhaust valve seats 21 lso that the water from the pump is carried directly to the exhaust valve seats. A small openingr 25 made in the pipe 25 at its lowestpoint `vso that water will dra-in from the pipe when it is desired to remove all the water from the svstem.

if'hile in some cases it has been found` that goed results are obtained by carrying the water directly to the Valve seats as hereinabove described, yet in others it has been found that the valve seats are cooled more effectively by, and infact require the additional cooling properties of, a cooling systern which not only supplies the water directly to the exhaust valve seats, but also carries the water away from points above y This part of the invention is particularly shown in Figsa and 5 where it is seen that a pipe 3l extends down into the cylinder casting from the top there nl and to a point just above each' of the exhaast valve seats,` andeach of these pipes communicates with branches 32 of a pipe 14a which leads to thc radiator.

lie some cases it has been found suflicient andeven desirable that the water should becariied to the cylinder block and delivered to lthe jacket at one point, as in the old systems. when the outlet from the cylinder block is arranged as shown in Fig. a, that is with the pipes 3l leadingir to points just above the exhaust valve seats.V In others, however, the water is carried to the exhaust valve seats and the pipe 3l is omitted. In still others both the pipe or 25 and the pipes 3l are used.

lt will he understood that by thus directing the tgreater part of the cooling effect of the water onto the exhaust valve seats`r those seats are kept relatively cool and tll're- Va point above and It will be.` further understood that other forms than those shown may beused withoutdeparting from the spirit or scope of the invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

l. In a hydrocarbon motor. the combinan tion with a jacke/ted cylinder having an eshaust valve seat, of means for feedingr water to the interior of thecylinder jacket directly to a point between the cylinder wall and said seat and withdrawing it from the opposite side of saidA seat.

2. In a hydrocarbon motor7 `the combination with a jacketed cylinder having an exhaust valve seat at one side thereof, of means for feeding water to ythe interior of'said jacket directly to a point below and at one side of said seat and withdrawing it from seat.

3..In a hydrocarbon motor, the combination with a jacketed cylinder having an eX haust valve seat at one side thereof, of means for feeding water to the Vinterior of said and the seat and withdrawing itfrom a point above and at the other side of said seat.

4. ln a hydrocarbon motor, the combination with a jacketed cylinder block having inlet and exhaust valve sea-ts, of a pipe cast into the block inside of said jacket and extending crossiviseof the block between two 105 cylinders, said pipe having branches leadinlcuto points beneath exhaust valve seats.

5. In a hydrocarbon motor, a cylinder block having a water pipe cast therein, said pipe having main outlets therein and a drain hole at its lowest point.

6. In a hydrocarbon motor7 ,a cylinder block having a water pipe cast therein7 said pipe having main outlets directed upwardly y, and a drain hole at its lowest point.

T. In a hydrocarbon motor, a cylinder block having a water pipe castJ therein.'said pipe extending diagonally upward towards its outlet and having,r a drain hole at its lowest point.

8. In a hydrocarbon inotor. the cornbinafA tion with a jacketed c vlinder havingan exhaust valve seat at one side of the cylinder. ot means for feeding water to the interior of) the cylinder jacket at a point at one side of 125 .said exhaust valve seat, and means formingr an outlet for said cylinder jacket arranged at the-opposite side otl said valve seat.

In testlniony whereof- 1l aiix in v signature.
